Short name: Tyr_Pase_rcpt_alpha

Family relationships

Description

This entry represents receptor tyrosine-protein phosphatase (PTP) alpha (EC:3.1.3.48). PTP catalyses the dephosphorylation of protein tyrosine phosphate to protein tyrosine, and appear to play a pivotal role in insulin receptor signalling. It can exist as a single-pass membrane protein or in the cytoplasm. PTP-alpha is as a positive regulator of Src and Src family kinases, acting to dephosphorylate and activate Src. As such, PTP-alpha affects transformation and tumourigenesis, inhibition of proliferation and cell cycle arrest, mitotic activation of Src, integrin signalling, neuronal differentiation and outgrowth, and ion channel activity [PMID: 12678847].
